Mori Nanako arrives on a temporary assignment. Upon reaching the office, she sees a male employee being scolded by his superior. His soft, big-titted appearance immediately catches her attention. She secretly comforts him, eventually letting him cum inside her mouth. Unbeknownst to her, the boss—secretly a masochist—forces her into face-sitting, plays with her feet, and cums from inside her stockings. While she's answering a phone call, he discovers she's not wearing panties and starts molesting her further, ultimately cumming on her glasses as well. A series of events where the office atmosphere blends with her irresistible charm.
